Sonata Strap help

 By: chikai168 : July 13th, 2020-08:59
Hi all, 

I hope that someone in the community who has changed the strap of a Sonata or Freak will be able to help. 

I have recently acquired the Streamline. Fantastic piece but I want to get an aftermarket strap which can bend at the spring bar. However, despite many many attempts, I cannot remove the strap! I have a Bergeon style spring bar tool and I cannot seem to grip the shoulders of the spring bars at all!

If anyone has been successful, I would be most grateful for some hints! What size and shape pilers did you use?

I have attached some close-ups of the spring bar. I cannot see the shoulders on one side......

Many thanks,
Chi Kai

Tweezers or watchmaker blade. The shoulder is there you just have to work it slowly and avoid scratching the case. Or visit your local watchmaker or AD. [nt]

I am trying to avoid a trip to the AD is possible! The only strap that I have ever had to get an AD to change was for Breguet.

In my photos, I can see the shoulder in the last one. But can’t really see it in the first two. Can you?

Don't take any risk, unless you have an AD or a strap maker where you live... [nt]

That may be the case Nicolas. I will probably just head into town to an AD when my new strap arrives.

It would be a pity to scratch it! [nt]

When I changed The Freak strap, it came right off.

I used my AP tool kit, the simple sprinbar removal tool.  As I depress one side of the pin in, removing it from the watch case pin recess, I then pried the strap down and away.  Meaning I sort of pulled / bent it away from where the curved part of the top side of the strap touches the case.  Should pop loose.  Obvious comment, but just be certain you have depressed the spring bar far enough to clear its attachment to the case, and then nothing else is holding it on.

Thanks Michael

I will have another go later but I may have to just admit defeat and head into town to my AD......

There is no shame in that!

Better to be safe. Keep us posted.

Will do. The new strap will take a few weeks to arrive anyways!
